Be it known that I, WILLIAM B., ARNOLD,

of North Abington, county 'of Plymouth, and State of Massachusetts, haveinvented an Improvement in Hinges',of which the follo'wing`idescription, in connection with the' accompanying drawings, is aspecification ,Y like lettersy on the'drawings representing like parts.

My invention is a new hinge, and has for its object the provision of ahinge having the general shape and ,advantages of a plug or doWel likehinge, while being exceedingly" cheap, strong, and light.

A number of dierent kinds of hinges have been proposed made'on thegeneral principle` of pivoting together vtwo do'welsor 4sets .ofvdowels, the dowels to be inserted in the wood of the material to behingedtogether and secured therein; but the high cost of Vmanufacture ofthese hinges as heretofore made has been practically prohibitive, andbesides this', being turned from solid metal they have been very heavyand cumbersome. I have invented a hinge of this general character whichis eX# ceedingly' light and maybe made with ex,- treme accuracy at avery slight cost, so as to be Within the reach of all, desiring such ahinge, my invention in its preferred'embodiment also possessing variousother advantages which will be more fully pointed out in the course ofthe following detailed description, reference being had to theaccompanying drawings illustrative of preferred emlmdi-V ments of myinvention, andthe latter willibe more-particularly defined in theappended claims. l

In thedrawings, Figure l is a perspective View of one form of Amy hinge;Fig. 2 is a top plan View of a hinge' of the samegeneral characterslightly modified. Fig. 3 is a perspective View of a furthermodification. Fig'. 4 is a broken detail in vperspective to be referredto.

Referring to the drawings, it will be seenv 'that each of the hingesillustrated is made up of opposite pairs of leaves stamped. or bent insemieylindrical shape, so as together to constitute a hollow plug ordowel like member of the hinge, the two members being pivotally joinedtogether at their pintle or turn- .ing-point.

. senti No, vonnis. un mail.)

each of which is stamped or bent to the shape of a semicylinder, eachleaf being provided at i-ts'inner end with an ear a', having a shouladra2, preferably formed on an arc of a circle concentricwith the pintlea3, and against the inner, sides of these ears a are similar ears orLo'f similar leaves a5, excepting that said ears argo-not stand outbeyond their leaves, as is the case at theshoulders a2 of the inclosingears a'. v

v In Fig. 2 the various parts are constructed the same as alreadydescribed, excepting thatv -instead of having the ears arranged just asstated I have offset the inner ears ai?, so as to provide shoulders a7,and have correspondingly osetv or' separated the outer ears as,

the shoulders a9 thereof being considerably Ydeepenthan the shoulders a?.of the' form shown in- Fig; 1, the shoulders of o? acting as abutmentsto bear against the adjacent wood and act as self-centering devices forinsuring that the pintles will be in accurate alinernent when a numberofthe hinges are to be used together adjacent each other.

In my hingel the opposite leaves oi" each pluglike member constitute asingle tube ex- ;tending to the pintle-ea'rs, these leaves being cut andstamped to form complementary parts of saidjtube and the two tubesWhengpivoted together at their ears forming a complete hinge; but I donot intend to restrict my invention to having both of the leaves of onetube precisely alike either in size or shape,

excepting thatwhen joined or formed together they shall make up onetube.

In Fig. 3 the'ears am a are brought closel f together and pivoted on onepintle a, this construction being preferable for the greatest strengthand compactness, although sacriiicing to some extent certain.advantagespossessed by the other forms of my invention alreadyexplained.v

In View of the above description it will be readily understood thatthese hinges can be manufactured at very slight cost, the leaves beingquickly and cheaplyv struck up ont of sheet metal (steel, brass', orother metal) on material'acoording to the use for which they arerequired and vquickly assembled and 4riveted or otherwise hingedtogether.

In case the hinges are made truly cylindrical they can be secured inplace simply by IOO `section they can be similarly secured by making thehole ywith any usual mortising-machine, the plug-like ends being theninserted any other suitable means. In some situations, however, it isdesirable that the leaves of these hinges shouldbe incapable of turningindependently on their pivots,as shown in Fig. 4, and accordinglyIprovideinterlockin g portions in any suitable manner to prevent theleaves from getting out of relative position, one form ofsuch-interlocking or holding device being shown in Figs. 2 and', whereit will-be seen that I have bent atongue inwardly atthe edge of eachleaf, said tongue being bent inwardly just sufficiently toV lap over andagainst the opposite edge, as is clearly shown in Fig. 3, the resultbeing that neither leaf can possibly shift on the other leaf.

I do not claim, broadly, a plug or dowel like hinge, inasmuch as I amaware that it is old; Vbut myV main endeavor has beentode- ,Y vise aVhinge of this vvery desirableV general character which shall ybepractical and commercially feasible, and the hinge herein disclosedmeets all the essential requirements so far as known to me, inasm uch asthese hinges can be made with exceeding rapidity and at very low cost,while being at the same time unusually strong, very light, and at thesame time they possess all the accuracy and neatnessV afforded by theexpensive turned hinge.

`I do not limit my invention to the particu- .lar forms herein shown,inasmuch as very many other shapes, certain of which have been alludedto, and various modifications and changes may be resorted to within then sitely-bent leaves against Vrelative. shifting movement, substantiallyas described.

2. A hinge, having hollow, plug or dow'el like memberspivotallycounectedat their-inner ends, each of said members beingcomposed "of twoV leaves oppositely bent to form complementary parts ofa single tube extending'to'adjacent the pintle and terminating inopposite ears, the several ears of the two opposite tubular parts beingVpivoted together,

substantially as described.

3. A hinge, having hollow, plug or dowel like members pivotallyconnectedat their inner ends, each of said members being-composed of twoleaves oppositely bent to form complementary parts of a'single tubeextending to adjacent the pintle and terminating in opposite ears, theseveral ears of the two opposite tubularfparts being pivoted together,.and certain of said ears being offset to provide projecting shoulders,substantially as described.

4. A hinge, having hollow, plug or dowel like members pivotallyconnected at their in- Vner ends, each member being in the form of asingle tube extending to'adjacent the pintle and terminating in oppositeears, said several ears of the two opposite single tubular parts beingVoverlapped and transversely pivoted together, and all of said ears beingoffset and circular in shape to provide shoulders for self-centering thehinge when in operative position, substantially as described'.

, 5. A plug-hinge whose members are cylindrical in. shape, said memberscontaining leaves pivoted together at their inner ends and extending inopposite directions, one or more of said leaves being stamped or bentinsemicylindrical form, substantially as dcscribed.

6. The herein-described hinge, having a member formed with oppositeleaves extending from the hinge-pintle and stamped or bent insemicylindrical form, together constituting a tubular plug-like end,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence oi' two subscribing witnesses.
